Battery condition monitoring system for batteries connected in parallel
First Claim
1. A system for monitoring the condition of at least two batteries connected in parallel under load, said system comprising:
- means for obtaining a voltage for each battery proportional to the current generated by each battery;
means for determining whether said battery current generated by one of said batteries exceeds said battery current generated by another of said batteries by more than a maximum allowable amount;
means for providing a visible indication whenever the current generated by one battery exceeds said battery current generated by said another battery by more than the maximum allowable amount.

Abstract
Disclosed is a battery condition monitoring system that monitors the condition of batteries connected in parallel in order to determine that each battery is generating the necessary power. The system determines the difference in voltages that are proportional to the currents generated by the batteries. The system compares the voltage difference between the currents that is a positive value to a predetermined reference voltage which is the maximum allowed difference in the battery currents. If the positive difference value is greater than the reference voltage, one or more LEDs will illuminate indicating that one or more of the batteries is weak or defective, uniquely identifying the battery or batteries.
